Kelly faced batters Friday for what amounted to three innings of work, Steve Gilbert of MLB.com reports.
Kelly threw a total of 50 pitches and looked "very crisp," according to manager Torey Lovullo. The right-hander is the presumed front-runner to claim the No. 5 starting job, a spot that was slated for Mike Leake before the veteran opted out for the 2020 season.
